    Influenza A virus subtype H1N1, also known as A(H1N1), is a subtype of influenzavirus A and the most common cause of influenza (flu) in humans. Some strains of H1N1 are endemic in humans, including the strain(s) responsible for the 1918 flu pandemic which killed 50–100 million people worldwide. Less virulent H1N1 strains still exist in the wild today, worldwide, causing a small fraction of all influenza-like illness and a large fraction of all seasonal influenza. H1N1 strains caused roughly half of all flu infections in 2006. Other strains of H1N1 are endemic in pigs and in birds.

    In March and April 2009, hundreds of laboratory-confirmed infections and a number of deaths were caused by an outbreak of a new strain of H1N1

    Influenza A virus strains are categorized according to two viral proteins, hemagglutinin (H) and neuraminidase (N). All influenza A viruses contain hemagglutinin and neuraminidase, but the structure of these proteins differs from strain to strain due to rapid genetic mutation in the viral genome. Influenza A virus strains are assigned an H number and an N number based on which forms of these two proteins the strain contains.

    The Spanish flu, also known as La Gripe Española, or La Pesadilla, was an unusually severe and deadly strain of avian influenza, a viral infectious disease, that killed some 50 million to 100 million people worldwide over about a year in 1918 and 1919. It is thought to be one of the most deadly pandemics in human history. It was caused by the H1N1 type of influenza virus.

    甲型H1N1是我們俗稱的「豬流感」的正式稱號,

    由於其他國家及市民誤會此流感由豬傳播,

    會影響豬肉的入口,

    所以才轉回改稱甲型H1N1。

    甲型H1N1流感同豬流感是冇分別的!

    只是政府不想市民以為豬流感是由豬傳染,所以改為甲型H1N1!

    2 號 很好 !

    豬流感病毒,是豬群中一種可引起地方性流行性感冒的正黏液病毒(Orthomyxoviruses)。目前在實驗室裡所分離出來的病毒,多被辨識為丙型流感病毒,或者是甲型流感病毒的亞種之一。在香港,「人感染豬流感」又名「人類豬流感」。

    電子顯微鏡下的H1N1型流感病毒豬流感有很多個不同的品種,計有:H1N1、H1N2、H3N1、H3N2和H2N3亞型的甲型流感病毒都能導致豬流感的感染[1][2][3]。

    投我一票!
